| Abstract | ||
| When a silicone maxillofacial prosthesis is no longer clinically useful after 1.5 to 2 years, a new prosthesis should be made. Adding some kinds of nano-oxide fillers could enhance the situation and address this issue. This study sought to determine how the CaCo3 nanofiller affected the maxillo facial tear strength of Silicone elastomer RTV50F after artificial aging for 200 hours. Eighty samples in total were split into two groups, each of which having 40 samples, which are then subdivided into four groups: the control group, 0.5%, 0.75%, and 1%. Samples in the prior concentration groups were subjected to rip strength tests both before and after 200 hours of artificial aging. ANOVA and Tukey\'s HSD tests were used to analyze the data and determine the differences among groupings. Scanning electron microscopy (SEM) and Fourier-transform infrared (FTIR) analysis also used. The ANOVA test show Both before and after aging, the silicone elastomer\'s mechanical quality (tear strength) was enhanced by the inclusion of CaCo₃ nano-particles. The best results were obtained at a concentration of 1% CaCo₃ (D group), the efficiency of CaCo₃ in reinforcing silicone is supported by these data. The results showed that the addition of CaCo3 to VST-50F silicone showed significant difference compared to the control group. Finally, one can draw a conclusion stating that the addition of calcium carbonate (CaCo3) nano particles as filler improves and increase the tear strength of silicone elastomer both before and after being artificially aged for 200 hours. | ||
